— Jake Daniels, Industrial building
“They explained the installation process better than any other roofer we met with, it was obvious they know what they are doing. I can’t say enough about the easy online process of getting an estimate with out the hassles of the dog and pony show that the other roofers wanted to do on top of the roof”
— Muhammad, Commercial bldg
“We met with 5 roofers and GenSun was the easiest to work with. they explained all options and even gave us a quick quote for all options…no secrecy, no need to meet on top of the roof, just a low price. After I liked there price, they sent a person to do an inspection and they even lowered the price after the inspection…so honest!”
— Ira Goldstein, Office building
